SPECIFICATION forming part of Letters Patent No. 553,240, dated January21, 1896.

Application fil $eptember 12, 1895. Serial No. 562,302. (No model.)

To all whom it may concern:

Be it known that I, GEORGE O. HOUSER, a citizen of the United States ofAmerica, residing at Hagerstown, in the county of \Vayne and State ofIndiana, have invented certain new and useful Improvements in RollerCopying-Presses; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to whichit appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of this invention is to provide a roller copying-press inwhich the rollers are held in frictional contact with each other so thatwhen one is turned the others will be turned therewith, a mainadjustable roller being provided which is covered with a fabric andlocated above and between two rollers over which an endless belt passes,said belt entering a pan of water so that it will be moistened, the panalso serving to connect the lower ends of the side pieces of the pressto each other and also forms a rest or support for a shelf which isattached to the side pieces of the press.

The invention consists in the specific construction and combination ofthe parts, as will be hereinafter fully set forth, and particularlypointed out in the claim.

In the accompanying drawings, forming part of this specifiation, Figure1 is a perspective view of a roller copying-press constructed inaccordance with my invention. Fig. 2 is a vertical sectional view. Fig.3 is a detail sectional view, and Fig. 4 is a detail perspective view ofone end of the presserbar which adjusts the main roller.

A A designate the side pieces of the press, which are preferablycastings formed so as to provide supporting-legs a a, which are adaptedto be bolted or otherwise secured to a platform. The side pieces arealso provided with a transverse web or flange a and inwardlyprojectingside flanges M, the transverse flanges being provided with recesses,which form bearings for the lower rollers. The upper ends of the sidepieces are connected to each other by a plate 13, which is providedcentrally with a screw-threaded aperture through which a screw B passes,said screw having a hand-wheel at its upper end.

0 designates the presser-bar, which is provided at its ends withdepending portions C having extensions 0 providing bearings in which theends of the upper roller, D, bear. The-roller D is preferably made ofmetal and has the journals turned on the ends thereof. The surface ofthe roller is covered by a fab ric d made up of felt with a rubberbacking.

E and E designate the lower rollers, which are j ournaled in therecesses in the flanges a of the side pieces A, a journal of one of therollers passing through an opening therefor in one of the side pieces toreceive an operating-handle. An endless belt E passes over the rollers Eand E, and is composed of a facing of absorbent felt with a backing ofrubber, the rubber giving it sufficient hold upon the rollers.

F designates a pan having a bottom f, with an upwardly-inclined frontportion, side pieces f, and a rear wall f, the rear wall extendingupwardly beyond the side pieces. The'rear end of the pan is providedwith projecting lugs f through which pass screws for connecting said panto the side pieces A of the press, the front end of the pan being alsoconnected to the side pieces by screws, as shown in Fig. 2.

It will be observed that the pan and top plate B secure the side piecesA A of the press to each other so as to retain the rollers in position.

G designates a shelf, which is provided at its rear end with lugs g,which enter recesses in the side pieces A A to pivotally connect theshelf thereto. When the shelf is lowered to a horizontal position itwill rest upon the front end of the pan, and when not in use it may beswung up so as to lie against the frame of the press to occupy butlittle space. Another object of having the shelf pivoted to the frame isthat when it is swung up a space will be provided by which water can bepoured into the pan.

hen the parts have been assembled as shown and described and waterplaced in the pan and it is desired to use the copying-press, the handleis turned several times to thoroughly moisten the belt, thecopying-paper-- one or more sheets-is then placed upon the shelf so thatits inner end will engage the belt, and the letter or other matter to becopied is placed thereon. Now the handle is turned slowly, which turnsthe rollers and draws the papers between the roller D and endless belt Ethe hand-wheel having been previously turned to insure proper pressure.

By forming the presser-bar C as herein shown and described a slightrocking movement will be permitted, which will insure the properpositioning of the roller D between the rollers E and E.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a roller copying press, the combination with a frame consisting ofside' pieces A, A connected at their upper ends by a cross-piece Bhaving centrally a threaded aperture, the side pieces havinginwardly-projecting side flanges a and a transverse flange a, the latterbeing provided with recesses forming bearings; of a pan connected to thelower part of the side pieces; a movable cross-bar 0 having dependingbearings c at its ends, and a screw B engaging the threaded aperture inthe crosspiece so as to bear upon the cross-bar; together with a rollerD j ournaled at its ends in the bearings c of the cross-bar; rollers Eand E j ournaled in the recesses in the transverse flange a, and anendless belt passing over the rollers E and E, said belt entering thepan F and engaging the rollerD between the rollers E and E,substantially as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE C. IIOUSER. Witnesses:
